Converters should have one property per bank type
As noted in Moore#184 (closed) because the Allen converters request a single monolithic raw event, they require an additional converter to build this monolithic raw bank when running on simulation (or data) files where the raw event has been split. We should consider giving the Allen converters one property per required bank type, so that they can process files regardless of whether the raw event is split or not without requiring additional converters to be added to the sequence.
